SPEED AND msrlaircn INVDIGATING AND nnoonnnve DEVICE.

- i To all whom may concern."

Be it known that I, .WILLIAM A. Gius- 2 won), a citizen of the United States, .residlng at Sharon, in the *county of Medina and State of Ohio, have invented certain new and useful Improvements in Speed and Distance Indicating and Recording Devices, of

which the following is a specification.

The present-invention relates toa com specification of Letters Patent.

bined clock and speed and distance indi-' eating and recording device.

- An" important'objectof nay-invention is to provide "means of the above mentioned character," whereby the speed of an auto; mobile or other vehicle,may be accurately recorded with respect to the time, so that I the exact speed at any given time during the-travel maybe ascertained. L

A further object of this 1nvention 1s to provide a device of the above ment oned character, which is compact in, arrangement of parts, so that the device will occupy the mlnimum amount of space, neat inappear ance, and reliable in 0 eration.

hands? and S are provided, which are moved by the ordinary form of clockworks to -be referredto; 'The dial 6 is covered by a lid comprising an annular frame 9,

holding a section of glass 10 or other transparent material. The lid comprising the frame 9 is hingedto the forward'lid 4, as

shown at 11, wherebysaid lid may be opened and closed, suitable means being'provided to detachably-hbldth same in its closed position. Thelid 4 is further provided near the .dial 6 withan opening 12, preferably 7.

spanned by a section of glass or other transparent material, and'through which is seen 14 or other stationary indicator is formed An arrow upon thelid 4 adjacent the opening'-12, as I shown, to cooperate with the scale 13.- Theforward cover or lid 4 is provided preferably near itsupper right hand corner with an opening .spanned'by a section of trans- Iparent material 15, through which are seen figures 16 of an odometer .17 of any well,

known or preferred type.

Disposed within the casinglis a metal framework 18, preferably removablymounb ed therein. This frame-workholds clockworks 19'including a shaft 20 which oper- ,'ates the minutehand 8. Rigidlyniounted uponthe shaft 20 is a bevel-gear 21, engaging'a bevel-gea r 22, which isrigidly mounted upona vertical shaft 28,-as shown. Rigidly 'mountedu'pon the shaft 23 is a feed spool or drum 24, provided near. one

end thereof with teeth or prongs 25, to engagewithin perforations 26 formed through the longitudinal edge of a; record sheet 27. The preferred detail of construction of this record sheet will be given hereinafter.

' The numeral'28 designates a carrying spool, which is mounted upon a vertical shaft 29, suitably journaled through portions of the frame-work 18. The numeral designates a take up spool or drum, which is rigidly mounted upon a shaft 31, vertically disposed and carrying at its upper end a bevel-gear 32, 'as shown. This bevel-gear is driven by a bevel-gear 33, which in turn is rigidly connected with a shaft 34. The shaft 34 receives its rotation from a spring motor including a spring 35, having connection with the shaft 34 through the medium of gears 36, as shown. It is thus seen that the take-up spool 30 will wind' up the record sheet 27 and that the longitudinal movement of the record .sheet is controlled by the rotation of the feed spool 24. The function of the teeth 25 carried by this feed spool, is to prevent the record-sheet 27 from slipping thereon. As clearly shown in Fig. 5, the record sheet 27 passes over a fixed guide 37, and is engaged adjacent- -it by a marking device to be described. V

A vertically disposed shaft 38 extends near and parallel with the take-up spool 30, as shown in Fig. 2, and is rigidly connected with the frame-work 18. A slide rod 35) is provided near its ends with sockets 40, which receive the fixed shaft 38- and travel longitudinally thereof. A horizontal arm ll extends behind the slide rod 39 and the fixed rod 38 and is soldered orotherwise rigidly connected with said slide rod, as

' shown ate-2 but has no connection with the fixed rod 38. 'Rigidly connected with the end of the arm 41 that is adjacent the takeup spool 30, is a vertically disposed plate 43, upon the lower end'of which is rigidly mounted a sleeve or tube 44, included in the marking device. This sleeve or tube may preferably besoldered to the plate 13.

1 have shown this marking device more clearly in'Fig. 4, wherein the numeral 45 designates a removable inner sleeve fitting in the outer sleeve a l, which outer sleeve is rigidly connected with the plate 43, as above stated. 'The outer sleeve 44; has one end portion thereof tapered and split, as shown. the same being externally screwthreaded for receiving a clamping nut 46. It is thus seen that by proper manipulation of the nut 46 the sleeve 45 may be rigidly locked within the sleeve 44. Slidably I mounted within the tube 'or sleeve a5 is an element 47 preferably formed of indelible graphite. This element 47 is held in engagement with the record sheet 27' by a push- -pin 48. disposed within the sleeve4e5 and having its outer end. looped. as shown at 49. for connection with a retractile coil spring 50, the opposite end of which is connected with the plate 43, as shown. Attention is called to the fact that the element 47 engages the record sheet 27' at the point of engagement that said record sheet has with the fixed guide 37. r I

Disposed to one side of the fixedshaft 38 is a rotatable shaft 51, vertically disposed and extending in parallel relation to said shaft 38, as shown. This shaft is journaled tion with a flexible driving shaft (not shown) which is properly geared to the wheel of the automobile or other. vehicle.

The numeral 55 designates a centrifugal governor, comprising links 56 and 57, having their outer ends pivotally connected with sleeves 58 and 59, respectively. The adjacent ends of the links 56 and 57 are pivotally connected with weights 60. The sleeve 59 is loosely mounted upon the shaft 51 and is capable of moving longitudinally thereof. This sleeve 59 is provided with spaced flanges 61, between which is disposed the forked end 62 of the arm 41. The sleeve 58 is rigidly mounted upon the shaft 51 and carries oppositely extending pins 63, which in turn carry spring yokes 64, portions of the material of said spring yokes being coiled about the pins 63. Attention is called to the fact that the links 56 do not engage the spring yokcs 64 until said links;

rigidly mounted upon a shaft 67 which is journaled through bearings supported by a plate 68'. This plate is connected with the casing 1 and with the frame-work 18. i The upper end of the. shaft 51 is journaled. through plate 68. Rigidly mounted upon the shaft 67 is a bevel-gear 69, engaged by a smaller bevel-gear 70 carried by a shaft 71. At its opposite end, the shaft 71 has a bevelgear 72 rigidly connected therewith engaging a bevel-gear 73, whiclrdrives the internal mechanism of the odometer 17.

Thesca-le 13 is ruled or marked to indicate figures from zero to sixty, to represent the number of-miles per hour that the automobile or other vehicle is'traveling. Attention is called tothe fact that the spaces between the marks designated by the numbers decreasetoward the lower end of the scale 13. This is done sothatthe horizontal or speed markings of the scale 13- will correspond to the horizontal or speed markings of the record sheet 27, as will be apparent hereinafter. The scale 13 is soldered or otherwise rigidly connectedwith the sleeve 44 k the record sheet 27.. I preferably construct at 7 5, indicating that this portion of the record sheet is to be employed on the first day of the month. Other day sections are correspondingly designated. Each day sec tion is divided by vertical h ur-{lines-76, there being twelve a. m. hour sections and twelve p. m. hour sections. Each hour section is subdivided into half-hour sections by a vertical half-hour line 77. Each halfhour section is subdivided into quarter-hour sections by vertical quarter-hour lines 78. Each quarter-hour section is subdivided into five-minute sections by vertical five-minute lines 79. In practice I may print the lines 76, 77, 78 and 79 in different colors so that they may be more readily distinguished.

The record sheet 27 is provided with horizontal speed lines, designated by the numerals O, 10, 15, 20, 25, etc, as shown. Attention is called to the fact that the spaces between the horizontal speed lines decrease gradually toward the .upper edge of the record sheet, in a corresponding manner to the decrease of space between the lines of the scale 13, except that the decrease of the spaces between the lines of the scale 13 is toward the opposite endof the record sheet. The operation of the entire apparatus is. as

follows:The shaft 54 being properly geared with the wheel ofthe automobile or other vehicle receives its rotation therefrom, which rotation is imparted to the shaft 51. The shaft 51 being vertically disposed, the centrifugal governor 55 is controlled by gravity. The rotation of the shaft 51 causes the weights to move outwardly and through the medium of links 57 effect an upward movement of the sleeve 39 along the shaft 51. The arm 41 is accordingly elevated carrying with it slide rod 39 and plate 43. The scale 13 1s moved upwardly and the operator can observe through the opening 12 the rate of speed of the vehicle. The marking device including the lead element 4 i caused to travel with the plate 43 and marks uponthe record sheet 27 the graphic line. The horizontal speed lines of the record sheet indicate with relation to the graphic line the speed at which the vehicle travels.

' The clockworks turn the feed spool or drum 24 at such a speed that the space between two of the lines 79 of the record sheet isadvanced every five minutes. The take-up spool 30 is turned by the spring motor to wind up the record sheet 27 inaccordance with the speed at which the same is fed by the spool 24. The vertical times lines cooperate with the graphic line to indicate at opposed by both what time'a certain speed is obtained.' hen the speed of the shaft 51 is increased greatly the links 56 are moved upwardly to engage the spring elements 64 and it is obvious that the upward movement of said links 56 is gravitation and the springs 64. For this reason the space bet-ween the horizontal speed lines of the record sheet are decreased toward the upper edge of said record sheet and for the same reason the space between the lines on the scale 13 is decreased toward the lower end of said scale. The rotation of the shaft 51 is imparted to the gear 7 3 which operates the internal mechanism of the odometer 17.

It is to be understood that the form of my invention herewith shown and, described is to be taken as a preferred example of the same and that certain changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus claim 1. In a device of the character described, an upstanding rotatable shaft, a centrifugal governor carried thereby and including an upper sleeve rigidly connected with the rotatable shaft and a lower sleeve loosely mounted thereon, means including clockworks for advancing a record sheet, marking means to engage the record sheet, connecting means between said marking means and said lower sleeve, whereby said marking means is automatically moved by the centrifugal governor, ing means for movement therewith, and stationary means to cooperate with the scale to point to figures thereon.

, 2. In a device of the character described, an upstanding shaft, a centrifugal governor carried thereby, ing arms adapted to move in a substantially vertical plane, a spring carried by the shaft and normally spaced from the arms and engaging said arms only when they are swung upwardly by centrifugal force when the device is operated very quickly, whereby said swinging arms are controlled during the first part of their travel by gravity and hence their operation is accurate and sensitive, means for advancing a record sheet, and marking means operated by the centrifugal governor.

In testimony whereof I aifix my signature in presence of two witnesses.
